Residents will likely have to stay up late to see any snow falling over Lancaster County.

There is a chance of rain and snow tonight before 11 p.m., then snow is expected to fall after 11 p.m., with accumulations of less than half an inch, according to the National Weather Service. Any snow that falls isn't expected to stick around long, forecasters say.

The possibility of snow will usher in cold weather for the weekend. Friday will be mostly sunny with a high of 35 and Friday night's low will be 19.

As Democrats in Congress work to finalize a health-care bill, Lancaster is gearing up for its fourth TEA (Taxed Enough Already) Party on Saturday.

The event will be held outside the Bradley Arts and Sciences Building at the University of South Carolina at Lancaster. If the weather is too cold, the event will be moved inside. The event begins at 11 a.m. and should last about two hours.
